SAFETY-RAZOR.

Specification of Letters Patent. Patented Sept. 26,

Appliation mea June 22, 1915. serial No. 35,723.

TQ all/whom t may concern Be it known that I, ARTHUR M. MoNIoHoL, asubject of the King of 'Great Britain, residing at Yorkton, in theProvince of Saskatchewan and Dominion of Canada, have invented new andusefulA Improvements in Safety-Razors, specification.

The invention relates to safety razors, and more particularly to theclass of automatic safety razors.

The primary object of the invention is the provision of a safety razorwherein the blade thereof is in strip form andadapted to automaticallymove across .the working face of the holder so as to effect an angularcutting action when the razor is drawn over the face for shavingpurposes.

Another obj ect of the invention is the proof which the following is avision of a razor of this character wherein the strip is made flexibleand endless so that it will be guided over a pair of rollers to presenta continuous cutting edge lmovable under the action of a spring foreffecting the angular cutting operation.

A further object of the invention is the provision of a razor of thischaracter which is novel in form to assure a positive operation and afresh cutting edge during the continued use thereof.

A still further object of the invention is the provision of a razor ofthis character v which is simple in construction, reliable and eflcientin operation, and inexpensive inl manufacture.

With these and other objects in view,/\the invention consists intheconstruction, com-` bination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claim hereunto appended.

In the drawing Figure 1 is a side elevation of a razor constructed inaccordance with the invention. Fig. 2 is an end elevation thereofwith-the housing broken away. v

Fig. 3 is a sectional view on the line 3 -3 of Fig. 1. Fig. 4 is a viewsin the drawing.

Similar reference characters indicate corresponding parts throughout theseveral sectional view on the winding of a coiled main spring 7 which islnclosed within a case 8 rotatably journaled wlthin the housing 6, thespring being fixed to the stem or handle 5 and the casing 8,respectively. Formed on the casing 8 lat its periphery are, gear teeth 9which serve as the main driving element, and meshes with a gear 10 whichalso meshes with a driven gear 11 fixed to one of a pair of axles 12journaled in spaced parallel relation to each other 1n opposite cheeksof the housing 6. The gear 10 meshes with the pinion 12 which 1sconnected with a suitable speed regulator 13 for controlling the'actionfof the spring when the razor is in use. Fixed to the axles 12are guide pulleys 14 over which is trained an. endless flexible cuttingblade 15, the same being acted upon by means of a tightener 16 of anyapproved form, which-.serves to hold the blade taut. blade 15 travelswithout the working face 17 which carries a guard portion 18 of anyordinary form adapted to shield a thin blade in cutting position. V Thelhandle 5 is provided with a suitable ratchet wheel 19with which engagesa ratchet pawl 20 pivoted to the handle 6- and suitably held in workingrelation to the ratchet wheel for the locking of the handle to preventthe turning thereof in one direction to resist the tension of the spring7 when wound. i

When the spring 7 is wound by the turning of the handle in the reversedirection the said spring acts upon the gears 10 and 11 for the drivingof the blade 15 across the working face of the housing 6 so that whenthe razor'is in use the blade will effect a.

-therefore a more extended explanation has 'I 100 been omitted.

What is claimed is A safety razor comprising a substantially equilateraltriangular shaped housing hav' lng a guard formed in one straight sidethereof, pulleys journaled interiorly of the housing an endless 4bladetrained over the pulleys and having a sharpened edge mov' guard, ahandle rotatably housing, a coiled mainable beneath the journaled inthespring having one end fixed to the stem, a spring casing looselyjournaled upon the The outer stretch vof the stem interiorly of thehousing and having 4 gear connections between the casing an one of thepulleys, a ratchet wheel mounted on the stem, and a locking pawl pivotedtov the housing and engageable with the 'ratchet wheel to lock the stemagainst rotation in one direction.
